Stacking bank notes in a cassette for an ATM

摘要

A device for stacking sheet documents 31 such as bank notes onto a stack 32 extending along a stacking axis 34 in a container 21 such as a cassette for an ATM comprises a sheet document input 7, 8b, 9b spaced apart from the top of the stack 32 in a direction parallel to the stacking axis 34; and at least one stacking member 15b to which the sheet documents 31 are fed from the sheet document input 7, 8b, 9b along a feeding direction, the stacking member 15b being closer to the top of the stack 32 in the direction parallel to the stacking axis 34 than the sheet document input 7, 8b, 9b, such that a first portion of the sheet document passing the stacking member 15b is bent by the stacking member 15b from the feeding direction to a direction parallel to the stack 32 and is thereby positioned on the stack 32. The trailing edge of a document 31 flicks down onto the stack 32 as it is released from the sheet document input 7, 8b, 9b. The stacking member 15b may float on the stack 32 to accommodate growth of the stack and the container 21 and/or input may be moved by a drive system 2, 3, 4 to maintain the input above the top of the stack 32. A removable liner 25 (fig. 3) may be inserted in cassette 21 whilst it is filled with the stack 32 of bank notes 31.
